O.R.

Definition from Nolo’s Plain-English Law Dictionary

Short for "own recognizance." A person who is charged with a criminal offense may be released without having to post bail if the judge is convinced that the person will honor his obligation to show up at future court appearances. Defendants who are good candidates for "O.R. release" are those who are unlikely to flee, namely, those with substantial ties to the community (property owners) and people with close and supportive family nearby.
